[Averton (P and C)]

We have been using Meteoblue to record the conditions of each of our observing sessions. There are three parameters given for seeing, one in arc seconds and two indexes that range from 1 (bad) to 5 (good). What is strange is that very frequently the arc seconds are quite low (around 1.0) but both the indexes are poor (1 or 2). We've never seen low arc seconds and high indexes. Today, however, there was agreement. The arc seconds was 3.38 and the indexes were 2 and 1 - basically poor seeing. And they were 100% correct.
In spite of this, there was blue skies, no clouds and no wind so we imaged anyway.
